HOLDER FOR DETACHED CUTTING-BLADES.

Specification of Letters Patent.-

Patented Dec. 2.], 1.909.

Application filed April 27, 1908. Serial No. 429,572.

T 0 all whom it may concern:

lie it known that I, Aa'riinn \V. BEAMAN,

a citizen of tl1c, U11ite t States, residing at \Vorcester, in thecounty of Worcester and Commonwealth of Massachusetts, have inventedcertain new and useful Improvements in a Holder forDetached(hitting-Blades, of which the following is a specification,accompanied by drawings forming a part of .the same, in which Figure 1is a. side view of my improved holder with a blade inserted. Fig. :2 isa top view of the same without a blade. Fig. 3 is a side view on anenlarged scale of the blade holding portion, with the gripping jawsraised to receive a. blade. 7 front end view of the blade holdingportion with a blade inserted. Fig. 5 is a rear end view of the same,and Fig. ti is a perspwtive view of the gripping jaws detached.

Similar reference figures refer to similar parts in the different views.

ltly invention relates to holders for detached cutting blades, in orderto furnish an opportunity for their manipulation in sharpening or forother purposes, and it consists in the construction and arrangement ofparts as hereinafter described and pointed out in the annexed claims.

I have shown the holder arranged to receive a blade from a safety razorand to hold it securely during the process of stropping, but] do notconfine myself to this particular form, and the principle of myinvention is applicable with slight changes for securing many otherforms of cutting blades which are separable from their operativehandles.

In the present embodiment. of my invention I have shown the holderdivided into two parts, a handle portion 1 and a blade holding portioncomprising a comparatively rigid cylindrical member 2 of sheet metal,with a longitudinal opening 3 in its top, into which is inserted anelastic elongated V- shaped member 4 also of sheet metal, with the baseof the V uppermost and Wider than the opening 3. At the base of the Vthe sides 5 and 6 of the V-shaped member 4. are bent inward andterminate in longitudinal gripping surfaces 7 which are arranged toreceive the blade 8. The V-shaped member is provided with an extension9, arranged to engage the cylindrical member 2 at 10 be yond the opening3, thereby forming a rocking surface upon which the V-shaped mem- Fig.lis a I ber 4 may be rocked to raise it from the opening 3, as shown inFig. 3, and thereby allow the gripping surfaces 7 to separate for theinsertion of a razor blade. The elastic V-shaped member 4 is constructedwith a sutliciently obtuse angle to allow its easy escape from theopening 3.

Near the apex 11 of the V-shaped member its sides 5 and (3 are connectedby spurs 12, which serve to limit: the downward movement of the blade asit is inserted. "In the present instance, these spurs are located neareach end of the V-shaped member, in order to contact with the razorblade near its end and beyond its cutting edge.

2 serves as a stop to prevent forward move.- ment of the blade, and theside 6 of the V-shaped member is offset to form an extension 13,approximately in the vertical plane of the gripping jaws 7, therebyproviding a. stop 14 to limit backward movement of the razor blade. Theextension 13 is provided at its lower corner with a spur 15, arranged tocontact with the cylindrical memberQ and limit the upward rockingmoven'ient of the Vshaped portion 4. After the razor blade is insertedbetween the gripping jaws 7 and its position determined by contact withthe spurs 12, the blade 8 and stop H, the V-shaped member is depressedby pressure upon the extension 1?), thereby rocking the V-shaped member4 upon its extension 9 and bringing it within the cylindrical portion 2.The sides and G'of the V-shaped member are compressed by contact withthe edges 16 and 17 of the opening 3 in the cylindrical member Qftheedges 16 and 17 being of suflicient rigidity to bring the gripping jaws7 into firm contact with the razor blade between them. i

When the V-shaped section has been depressed to the position shown inFig. 1, the

of the cylindrical portion'far enough to include a portion of the.extension 13, thereby preventing accidental escape of the V-shapcdportion from the cylindrical member, due to the elasticity of the sides5 and 6 and the character of the angle at the apex 11.

The handle 1 is provided with a raised tends slightly above thecylindrical member 2,thereby preventing rotation of thehandl e 1 uponthe cylindrical member 2. The grip The portion 10 of the cylindricalmember handle portion 1 is slipped over the end '18 portion 19 arrangedto contact with the upper surface of the extension 13, which expingsurfaces 7 are extended slightly beyond the sides 5 and 6 of theV-shaped por-' tion to provide a lifting shoulder 20, which afl'ords an0 portunity of engaging the V-shaped portlon to lift it out of thecylindrical member into the position shown in Fig. 3, when the handle 1is removed.

By my invention, as above described, I provide ripping jaws betweenWhicha cutting blae may be inserted, and means for determining theposition of the cutting blade held between said jaws. By the depressionof the V-shaped member between the sides 5-and 6 of the opening 3 thegripping jaws are closed and the cutting blade held firmly between them,and I also pro vide positive means for holding the V-sha ed member inits depressed position. The sides 5 and 6 are also arranged to divergesufliciently to allow an easy exit for the -V-shaped member frombetweenthe edges 16 and 17 of the opening 3, when the V-shaped member isreleased by the removal of the handle 1.

bent inward terminating in gripping surfaces, rigid surfaces separatedby a. distance less than the width of the base of the V- shaped member,an extension at the forward end of said.V-shaped member, andmeansconnecting said rigid surfaces arranged to engage said extension.

3. Ablade-holder, having an elastic V- shaped member with its sides atthe base bent inward terminating in gripping surfaces, av member havinga longitudinal 0 ening of less width than the base of sai ,V- shapedmember, with said V-shaped member arranged to be inserted transverselyinto said openin -shaped mem erprojectingfrom said open-' ing, and meansat either end of said opening for holding said V-shaped member withinsaid opening.

leaving the base of said V- 4. A blade holder, having a V -shaped memberwith elastic gripping jaws at the base of said V, a cylindrical memberhaving an opening of less width than the base of said V, with saidV-shaped member arranged to be inserted-transversely into said opening,and a detachable handle arranged to engage a portion of said cylindricalmember and cover one end of said opening.

5. A blade holder, havin an elastic V- shaped member with its si es atthe base bent inward terminating in gripping surfaces, a rigid memberhaving a longitudinal opening of less width than the base of saidV-shaped-niember, an extension on the forward end of said V-shapedmember arranged to engage said rigid member beyond said opening, meansforrocking said V-shaped member on said extension, and detachable meansfor holding the rear end of said V-' shaped member in said opening. I

6. In a blade holder of the class de scribed, the combination withanelastic V- shaped member provided with gripping surfaces, of acylindrical 'member provided with a longitudinal openingof less widththan the base of said V and arranged to receive said V-shaped member,means for rockin said V-shaped member upon its forward end in saidopening, and means for preventing the entire withdrawal of the rear endof said member from said opening.

7. A blade holder, havmg a V-shaped member provided with grippingsurfaces at v the base, means for opening and closing said V-shapedmember, and spurs arranged between the sides of said V-shaped membernear the apex to contact with the back of a blade insertedbetween saidgripping surfaces.

8. In a blade holder of the class described, the combination withelastic gripping jaws,

with said jaws bent inward to form gripping surfaces, rigid surfacesseparated by less distance than said jaws, and means for rocklng saidgripping jawsinto and out of engagement with rigid surfaces arranged toexert pressure upon said jaws and thereby bring said .gripping surfacestogether.
